Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Moisture Analyzers. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.

Original product description

EPVLF Transmission class cables vlf ac hipot tester General Information: VLF stands for Very Low Frequency. VLF is generally considered to be 0.1 Hz and lower, its major application is for testing solid dielectric cable, transformers, motors, generators, switchgear, and other electrical apparatus.

A VLF hipot is just an AC output tester but with an output frequency of 0.1 Hz or lower rather than 50/60. Hz. Although the frequency is very low, it is still an alternating current with polarity reversals every half cycle. At 0.1 Hz output, rather than 60.

Hz, it takes 600 times less current and power to apply an AC voltage to a capacitive load, like a long cable. Feature: Adapts microprocessor controlled, can realize voltage set-up/down, measuring and protecting automatically. Manual intervention is allowable even during the auto voltage boosting.

Touch screen, large LCD can display waveform clearly, and test report can be printed. Built-in printer Multiple protections (overvoltage protection, overcurrent protection at HV/LV sides). When the output is beyond the limitation, the control unit will shut itself down within 10ms.

Easy operation: simple wiring and operation. Safe and reliable: the controller and the high-voltage generator are connected at low voltage, photoelectrically controlled, safe and reliable to use. Closed-loop negative feedback circuit is adopted. No capacity rising during outputting. Large test range: 0.1. Hz, 0.05.

Hz and 0.02. Hz multi-frequency selection, large test range. Portable design, small size and light weight: it is very convenient for outdoor operation. Peak voltage: 30kV Output frequency: 0.1. Hz, 0.05. Hz and 0.02 Hz (selectable) Fuse: 10A Maximum load capacity: 1.1μ [ error: ≤3% Voltage waveform distortion: ≤5 % .

Working environment: Temperature: -10 ºC -+40 ºC , 85%RH. Indoor or outdoor Weight: 35kg Power supply: 220V 50/60. Hz The capacitance of the tested object shall not exceed the maximum rated capacitance of the instrument. Model Rated voltage Load capacity Fuse Weight EPVLF-34/1.1 34kV (peak 30kV) 0.1.

Buyer tips

  • State quantity range and split-delivery needs before price comparison.
  • Add certification, material or inspection standards when they affect acceptance.
  • For time-sensitive projects, include target arrival date and destination.
  • For special applications, describe operating condition, installation environment and duty cycle.

FAQ

What should buyers confirm first?

Confirm application, specification, quantity, destination and lead-time requirements before comparing offers.

Can buyers inquire when specs are incomplete?

Yes. Add model, material, size, use case and inspection needs in the RFQ to make replies comparable.

How should this listing be evaluated?

Check title, category, specifications and related keywords against the actual sourcing requirement.
